abstract：:The first step in DNA cleavage at V(D)J recombination signals by RAG1 and RAG2 is creation of a nick at the heptamer/coding flank border. Under proper conditions in vitro the second step, hairpin formation, requires two signals with spacers of 12 and 23 bp, a restriction referred to as the 12/23 rule. Under these cond...

abstract：:Ethidium causes the cleavage of DNA via a light and oxygen dependent process. Using covalently closed circular DNA as a substrate, the saturation kinetics and the dependence on superhelical density of the cleavage indicate that intercalated ethidium is mainly responsible for nicking DNA. Superoxide dismutase has littl...
